Our recent batch of releases (2.19.2, 2.20.0rc3 and 2.21.0.dev5) are all broken on arm64 macOS: they include x86-64 code for

psutil

, not arm64. https://github.com/pantsbuild/pants/issues/20765 I haven't dug into the cause other than what's in that issue. As noted in a comment, I've marked 2.19.1 as the latest (stable) release and added a note to the broken releases.

The self-hosted runner has Rosetta installed? By default?

yes

I would if I could 😉

Easiest review ever

It looks like the psutil workaround does paper over the arm64 macOS release problems in the 2.21.0.dev6 release there, so I've now prepped: • 2.19: cherrypick + rc release prep • 2.20: cherrypick + rc release prep Could someone review? Once those are in and validated, I think we should do a 2.19.3 stable release (essentially identical to 2.19.2, except working on arm64 macOS) and then can probably get the 2.20.0 stable release out too.

If no one else can sooner I'll be available probably in about 30-45m to review

Thanks for the review I'm not sure, sometimes the cherry picks have non-trivial changes from the parent (e.g. this case, I stripped out the ijson bump and just had the psutil one)

thanks a lot Huon. I haven't forgotten about the release manager changes, just had a crazy week this week: planning to do something about it next week.

all good, individual releases are easy with Josh's changes; just seems like it'd be good for the health of the project to spread the knowledge/decision making around a bit more 🙂
